Abstract

PURPOSE:To smoothly perform weighing work and to grasp the advance state thereof, by constituting the title scale so that the present excess and deficiency number to the calculated or weighing number of articles to be measured are displayed on one display device. CONSTITUTION:When the weighing number K0 is inputted from a keyboard 3, a numerical value M smaller than the number K0 is calculated according to a predetermined calculation method by a CPU 21 to be stored in a RAM 23 along, with the number K0. Next, a predetermined number N of specimens are placed on a tray 1a and the wt. W thereof is divided by a number N to calculate a unit wt. mu by the CPU 21 to store the same in a RAM 23. On and after, when a specimen is added, the wt. thereof is divided by the unit wt. mu to calculate the number K of the specimens. The calculated result is compared with the numerical value M and, at the time of K<M, the calculated number K is displayed on a display device 4. Further, a specimen is added on the tray 1a and, when K becomes larger than M, the difference P between the numbers K0, K is calculated to be displayed on the display device 4 as the number P to the added/removed. This operation is continued and, when the number K=K0 is formed, 'End' is displayed and a worker can know that weighing is completed.

<Prior art> Divide the weight of the unknown number of samples to be counted by their unit weight,
In general, counting scales used to determine the number of samples are used not only to simply determine the number of unknown samples, but also to weigh a fixed number of samples. In such weighing work, the worker must memorize the number of pieces to be weighed (hereinafter referred to as the number of pieces to be weighed).
It becomes necessary to compare the number of pieces with the displayed value and calculate the number of pieces to be added or removed.

<Problems to be Solved by the Invention> Conventional counting scales that have the function to smoothly carry out weighing operations as described above always require two displays, which is a drawback of increasing costs. There is. Therefore, it is conceivable to use only one display and configure the display to display the number of additions and removals when performing weighing work, but especially the maximum number of additions that is mathematically permissible. If a technology that displays the number of pieces that does not exceed the value Nmax is applied, Nmax will be continuously displayed on the display from the beginning of weighing, making it impossible for the operator to grasp the progress of weighing and causing work delays. It is expected that efficiency will decrease.
